GUIDE:
1. Fully turn the steering to the right to give access behind the driver's front wheel to work. [Removing the wheel will give more access but is not necessary.]
2. Remove the 6 screws holding securing the rear half of the felt wheel-arch liner in place using an 8mm socket. This will allow access without removing the arch-liner completely. Four of the screws are located in the wheel well itself and two are located underneath next to the sill.
3. Remove the plastic 'mud-guard' trim on the outside of the wheel-arch that adjoins the felt arch-liner. This is done by pressing the centre-pin of the 3 plastic clips through the clip and then removing the clips with a panel-popper tool. [It may be possible to do the job without removing this trim piece, as the clips are very hard to get out and prone to breaking, but visibility and access are certainly improved].
4. Peel the felt wheel-arch liner out from the rear lip of the wheel-arch and if possible tuck it behind the wheel. The washer-bottle should now be visible to the rear of the front wheel. It sits in a tight gap between the outer and inner wings of the car body itself and access is very limited. [This is unlike E39, E60 etc. where the bottle sits left-to-right across the rear of the wheel-arch and access if much easier!]
5. Remove the windscreen washer hose from where it enters the pump and move it out of the way.
6. Slide a long flat-screwdriver in between the washer-bottle and the outer wing and prize the pump upwards until the spout is clear of the bottle and the pump can wedged up and out of the way.
7. The clogged filter should now be sitting in the washer-bottle where the spout of the pump fits. Use the flat-screwdriver to prize the filter up and out of the bottle. It should now be removable by hand or using long-nose pliers / tweezers.
8. Clean the gauze filter using water and lightly brush it with a sponge-scourer or stiff brush. [I find an old toothbrush works perfectly.] It is likely clogged with a 'gel' like substance that builds up supposedly due to the use of incorrect washer-fluid as well as dirt from the bottom of the tank if the washer has been run without fluid in for a while, but should clean up pretty easily.
9. Carefully slot the filter back into the washer-bottle and press it back into place using long-nose pliers / flat screwdriver or both, making sure it is fully seated.
10. Slide the pump spout back into the filter / washer-bottle, making sure it is fully seated and rotated to the correct position with the spout for the windscreen-hose pointing to the side of the car.
11. Refit the washer-hose, trim, wheel-arch liner and wheel. [Reverse steps 1-5.]

many thanks - a lifesaver ! (well wallet saver!)
ReplyDeleteThis was going great for me until removing the pump and mine appears different. Mine has headlight wash (although headlights are washing fine) so i take it the instructions are different?
ReplyDeleteThanks,
Steve.
I also have headlight wash and the headlights are getting the right pressure. What was the final fix for you?
DeleteIn the end, I disconnected the tube from that comes out of the engine bay on the driver/right side (on a uk car) to the main rail that is under the bonnet and blew air with my mouth, quite hard but doable and then reconnected and pressure is back. I guess the gunk that was blocking the filter inside the reservoir is floating around somewhere for now. I might have to create some anti gunk potion soon and flush the system well but happy for now with the results. To disconnect and reconnect, there is a little black clip to remove and put back on, fairly easy to do so. When putting back on, just make sure the tube is pushed well onto the connector so no water leaks and pressure is full on. Thank you guys, glad I was able to sort it myself for now and not have to be charged through a dealer.
DeleteThat technique works for gummed-up screen wash in the tube but doesn’t usually clear filter blockages, so I guess that’s all you had. The filter will be on its way though.
DeleteIgnore my comment from yesterday, i was following the wrong tube. The instructions work, thank you!
ReplyDeleteyes, BMW have a habit of putting the larger, more obvious pump to the headlight-washers, yet I've never known one to get clogged, go figure
DeleteIs it a separate pump and filter for the headlight wash?
DeleteYes, not sure if the headlight pump even has a filter as I’ve never seen one blocked.
DeleteGreat instructions - many thanks. Managed to sort my filter out. It was very clogged and looked just like yours!
ReplyDeleteThanks for the great instructions - Mine was very clogged and looked just like yours even a preliminary cleaning attempt via air backflush though spray nozzles hose and a siphon backflush via tank. I still have weak flow in 2nd and 3rd spray nozzles. I guess some debris must have come through the line.

ReplyDeleteGreat article! Sorted mine right out, the filter was certainly a lot smaller than expected, and I had two 8mm bolts underneath too, so 8 in total for me (2012 535D M Sport).
ReplyDeleteNow for some new mud guard inner bits... lol
Are these instructions for LHD or RHD? Need to sort mine out tomorrow and want to make sure I'm removing the right wheel arch liner. Thanks!
ReplyDeleteInstructions are for RHD car, but the tank is in the same place. it would be the passenger side wheel-arch for LHD
DeleteAny idea how much bmw charge for this?
DeleteBe a couple hundred no doubt. Always seems to be the screen wash they recommend that gums the filter up too, that’s business.

ReplyDeleteExactly my problem. Spray was getting weaker and weaker until it finally stopped completely. Not much room with 20” wheels on but successfully cleaned the filter and got it all back together again. Result.
ReplyDeleteFantastic fix & concise details..thank you !
ReplyDeleteA bit of a fiddly job but very, very satisfying especially considering that I’ve saved myself a great deal of money. My filter was probably worse than the one pictured. Used a tooth brush and warm water
